According to WHO statistics, breast cancer (BC) disease represents about 2.3 million diagnosed and 685,000 deaths globally. Regarding histological classification of BC, the Estrogen (ER) and Progesterone (PR) receptors negative-expression cancer, named Triple-Negative BC (TNBC), represents the most aggressive type of this disease, making it a challenge for drug discovery. In this context, our research group, applying a well-established Virtual Screening (VS) protocol, in addition to docking and molecular dynamics simulations studies, yielded two ligands identified as 6 and 37 which were chemically synthesized and evaluated on MCF-7 and MDA-MB-231 cancer cell lines. Strikingly, 37 assayed on MDA-MB-231 (a TNBC cell model) depicted an outstanding value of 18.66 μM much lower than 65.67 μM yielded by Gossypol Bcl-2 inhibitor whose main disadvantage is to produce multiple toxic effects. Highlighted above, enforce the premise of the computational tools to find new therapeutic options against the most aggressive forms of breast cancer, as the results herein showed.
根据世界卫生组织的统计数据,乳腺癌(BC)在全球范围内的确诊病例约为 230 万例,死亡病例约为 68.5 万例。在乳腺癌的组织学分类中,雌激素(ER)和孕激素(PR)受体阴性表达的癌症,即三阴性乳腺癌(TNBC),是这种疾病中最具侵袭性的类型,这给药物发现带来了挑战。在这方面,我们的研究小组应用了一种经过充分验证的虚拟筛选(VS)方案,除了对接和分子动力学模拟研究之外,还生成了两个被鉴定为 6 和 37 的配体,这些配体经过化学合成并在 MCF-7 和 MDA-MB-231 癌细胞系上进行了评估。值得注意的是,在 MDA-MB-231(TNBC 细胞模型)上进行评估的 37 表现出了 18.66μM 的出色值,远低于棉酚 Bcl-2 抑制剂的 65.67μM,后者的主要缺点是会产生多种毒性作用。综上所述,这些结果证实了计算工具在寻找针对最具侵袭性的乳腺癌形式的新治疗选择方面的前提。
